[Dnsmasq-discuss] /etc/resolv.conf polling limitation

[Preston Crow]

I just ran into an interesting issue:

In my config, I set: resolv-file=/etc/resolv.conf.upstream

If I edit that file, I instantly see dnsmasq reload things as expected 
with various log messages.  That's good.

However, in my case, /etc/resolv.conf.upstream is a symlink.  If I 
change the symlink to point to a different file, dnsmasq doesn't 
notice.  I suspect it's using inotify to have the kernel tell it if the 
file is changed, and it isn't checking for a symlink that also needs to 
be watched.

I'm not sure if this qualifies as a bug.  If this is to be defined as 
the expected behavior, then I would suggest adding a note to the 
documentation on the polling pointing out that changes to symlinks won't 
be noticed.
